Mount Wangwu is a mountain situated about north west of Jiyuan City in China’s Henan province.[1] Located in the Wangwushan-Yuntaishan National Park, Mount Wangwu is a famous Taoist site that includes the “Celestial Grotto of the Small Pristine Void” (Chinese: 小有清虚洞天), one of the Ten Grotto-heavens of Taoism.[2]
According to legend, the Yellow Emperor used an altar on top of the mountain to offer sacrifices to Heaven or Tian (Chinese: 祭天) where he received the Book of Nine Elixirs (Chinese: 九丹經),[3] one of the earliest Chinese alchemical texts.[4]
